Cast deal takes 'Simpsons' to season 20

The Simpsons voice actors have signed a new deal which will take the show to its 20th season.

Production has been on hold for several months while the cast negotiated with show producer 20th Century Fox.

The actors have signed a four-year deal, covering them for seasons further than 20 as long as The Simpsons is renewed by Fox.

Salaries are said to have been increased to about $400,000 under the new agreement and Dan Castellaneta, who voices Homer, is becoming a consulting producer and writer.
